If you usually convert DivX AVIs in VCD or SVCD and have subtitles in text files (usually in SubRip or MicroDVD format that are commonly used with DivX) and want to encode subtitles within VCD/SVCD video using VirtualDub frameserving and Sub Station Alpha v2.x/4.x subtitling plugin for VirtualDub, this tool will help you to convert subtitles from text files to appropriate Sub Station Alpha (SSA) scripts that VirtualDub SSA plugin can process.

SUBtoSSA has many advanced options like setting auto-sizing mode where you can have automatic size adjustment for different fonts (to fit on screen), it can find longest text line from subtitle file for selected font styles so you can easily check will font fit on screen with your style settings, it support style savings for later useage in different material (with several predefined styles for different viewing modes I made), advanced options where you can change font settings for particular segment and part of text, saving complete work into project file for later modifications and more ...

Useage and features are optimized to make rather standardized subtitles and SSA scripts for useage in VirtualDub subtitler plugin so, some SSA features that are not relevant for subtitling and which are not supported by VirtualDub SSA plugin are not included and some features that are not SSA standard but supported by VirtualDub Subtitler are added.

This version support SubRip SRT native time-based subtitle format and MicroDVD frame-based subtitle file format. If you have subtitles in any other format (SubViewer, SAMI etc.), use some of conversion tools to convert them to one of supported formats (see links).
